1/2 c. brown sugar
1 tsp. dry mustard
1 tsp. prepared horseradish
1/4 c. cola-type soft drink
3 to 4 lb. precooked ham

Thoroughly combine brown sugar, mustard and horseradish. Moisten with just enough soft drink to make a smooth paste. Reserve remaining soft drink. Rub entire ham with mixture. Place ham in a crock pot and add remaining soft drink. Cover and cook on low setting for 6 to 10 hours (on high setting for 2 to 3 hours). I have made this without the horseradish.
